What is a Board Foot?

A board foot is a unit of volume, traditionally used for timber, equal to 144 cubic inches (12 inches long by 12 inches wide by 1 inch thick). 

Unlike softwoods, which are often sold by linear or square feet, hardwoods vary in width and thickness. Many lumber yards price hardwood using the board foot as the standard unit of measurement.
